PRODUCTION OF AQUEOUS SOLUTIONS OF CHLORINE DIOXIDE AND CHLORINE ABSTRACT OF THE DISCLOSURE Gaseous mixtures of chlorine dioxide, chlorine, steam and air are contacted with water to dissolve all the chlorine dioxide values and part of the chlorine values therefrom. The resulting mixture of chlorine and air is compressed and the compressed gas is introduced to the aqueous chlorine dioxide and chlorine solution to increase the amount of chlorine relative to chlorine dioxide absorbed in the solution. The resulting aqueous solution is used in pulp bleaching operations. Considerable water utilization savings are achieved by this procedure.
